Patent number: 10567728Abstract: A 3-D picture signal is provided as follows. An image and depth components having a depth map for the image are provided, the depth map includes depth indication values. A depth indication value relates to a particular portion of the image and indicates a distance between an object at least partially represented by that particular portion of the image and the viewer. The 3-D picture signal conveys the 3-D picture according to a 3D format having image frames encoding the image.

Patent number: 8345751Abstract: In a method for encoding and an encoder for a 3D video signal, center view frames, a depth map for center view frames and an occlusion data frame are encoded. On the basis of the depth map for the center view frame a distinction is made between functional and non-functional data in an occlusion data frame. This allows a strong reduction in bits needed for the encoded occlusion data frame. In the decoder a combined data stream is made of functional data in the encoded occlusion data frames and the center view frames. Preferably the center view frames are used as reference frames in encoding the occlusion data frames.Type: GrantFiled: June 19, 2008Date of Patent: January 1, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Reinier Bernardus Maria Klein Gunnewiek, Christiaan Varekamp, Wilhelmus Hendrikus Alfonsus Bruls

Publication number: 20120206453Abstract: A device converts three dimensional [3D] image data arranged for a source spatial viewing configuration to a 3D display signal (56) for a 3D display in a target spatial viewing configuration. 3D display metadata has target width data indicative of a target width W t of the 3D display in the target spatial viewing configuration. A processor (52,18) changes the mutual horizontal position of images L and R by an offset O to compensate differences between the source spatial viewing configuration and the target spatial viewing configuration. The processor (52) retrieves source offset data provided for the 3D image data for calculating the offset O, and determines the offset O in dependence of the source offset data. Advantageously the 3D perception for the viewer is automatically adapted based on the source offset data as retrieved to be substantially equal irrespective of the screen size.Type: ApplicationFiled: September 8, 2010Publication date: August 16, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Wilhelmus Hendrikus Alfonsus Bruls, Reinier Bernardus Maria Klein Gunnewiek, Age Jochem Van Dalfsen, Philip Steven Newton

Patent number: 8073292Abstract: When transforming a 2.5D video format to a plurality of images viewed from different virtual positions, it can occur that for certain output pixels, no input data is available. Therefore, these output pixels do not have any definite values assigned in their pixel locations. These unassigned pixel values cause artifacts called ‘holes’ in the transformed images. A method of hole filling or assigning pixel values in a region (110) comprising pixel locations of unassigned pixel values in an image (100) is provided. A direction (140) of an image feature (160) relative to a first pixel location (120) is estimated in a first neighborhood (130) adjoining the region (110) of unassigned pixel values. A second set of pixel values is selected from pixel locations in the estimated direction (140) from the first pixel location (120). A third set of pixel values are computed from the second set of pixel values.Type: GrantFiled: February 5, 2007Date of Patent: December 6, 2011Assignee: Koninklijke Philips Electronics N.V.Inventor: Reinier Bernardus Maria Klein Gunnewiek
